Managing personal Outlook.com account settings, security, and privacy
Thank you Brian for the response. I also have many emails from no-reply@microsoft.com in my Junk folder saying "unusual sign in activity" from russia, and asking me to click links to report this user. I logged into https://account.live.com/activity/ as you suggested as I did not see that suspicious activity on my account activity. Therefore I have deleted those emails without clicking those links. Thank you for your insight.
